RESUMO
A synthetic nonapeptide corresponding to the N-terminal sequence of poliovirus genome-linked protein (VPg) was linked to bovine serum albumin and used to raise antibodies in rabbits. The antipeptide antibodies specifically precipitated the nonapeptide, native VPg, and VPg-linked poliovirion RNA. The antipeptide antibodies inhibited host factor-stimulated, poliovirus replicase-catalyzed in vitro synthesis of full-length (35S) RNA in response to virion RNA. Oligouridylic acid-stimulated RNA synthesis was not affected by the antipeptide antibodies. Preincubation of the antibodies with excess nonapeptide reversed the antipeptide antibody-mediated inhibition of host factor-stimulated RNA synthesis by the poliovirus replicase. A role for VPg in the in vitro replication of poliovirus RNA genome is discussed.
